Description
The film electric heater is a heating element made of materials such as polyimide film. Its heating principle is to utilize the heat generated by the friction when an electric current passes through the film. This heating method has the characteristics of rapid heating, high efficiency and energy saving, as well as safety and reliability.
The film heater is an innovative heating technology that has positioned itself as an indispensable multi-functional solution for various industries. These ultra-thin and flexible devices offer a series of advanced features that surpass traditional heating methods, making them an ideal choice for a wide range of scenarios where traditional heat sources are insufficient.
Polyimide film heater is a semi-transparent, flexible and thin material, which is highly suitable for the manufacturing of etching foil heating pad. Due to its low thermal mass, excellent electrical insulation properties and excellent resistance, most chemicals allow for high power density and rapid and effective heat transfer. The thin and lightweight polyimide heater with a wide temperature range has obvious advantages over other forms of heating elements. In terms of rapid response, chemical resistance and low profile, polyimide heaters provide an ideal solution.
When purchasing the PI heating film, customers should pay attention to the differences in material thickness. The quality of the material will affect the service life of the product.
In particular, the production and processing techniques can affect the safety.
1) The maximum operating temperature of the PI heating film: 200℃; It can also achieve instantaneous and rapid heating to 300℃. The minimum ambient temperature is -40℃. Lower temperatures are prone to cause brittleness (including the failure of components such as the welding position of the heating film).
2) Maximum surface power density of the heating film: 31 W/cm²;
3) Voltage Usage: 1.5V - 380V can be selected and customized at will. Usually, the product shown here is a low-voltage product and uses around 12V; It is recommended to select a higher voltage for higher power consumption.
4) Voltage resistance strength: ≥ 2500V / 60 seconds. Generally, the voltage resistance of PI heating products can meet the requirements of 1200V / AC, which is sufficient for most customers.
5) Insulation resistance: ≥ 300 MΩ. Usually, it should meet the standard of 500 MΩ or above.
6) Power deviation: +5% to -10%. The designed power of new energy battery packs is all within 5% range.
7) The minimum manufacturing thickness is: 0.8mm, while the regular thicknesses are 1.0mm and 3.0mm.
Attentions Please:
After the customized polyimide film heater is purchased by the customer, it cannot be further cut or processed. Usually, the main body of the heating sheet does not reserve any leftover materials for subsequent processing. Any further processing would damage the heating element.
An important factor affecting the lifespan of the customized polyimide film heater is the impact of the customer's assembly process, namely whether the product is evenly attached to the heated object during the assembly process and whether there is any overheating phenomenon.
The applications of polyimide heaters are limitless, as they can be adapted to any situation requiring surface heating up to 200°C. From polar expeditions to space exploration, their suitability for harsh conditions has been proven. We are at the cutting edge of polyimide heaters!

The power deviation is +5% to -10%. The designed power of new energy battery power sources is all within 5% range.
Maximum surface power density of the polyimide film heater is 31 W/cm²;Operating voltage: 1.5V - 380V, customizable at will. Usually, the product shown here is a low-voltage model and operates at around 12V; when using this , it is recommended to select a higher voltage for higher power consumption.
Please pay attention to the operating temperature. Do not run the equipment beyond the normal operating temperature.
Polyimide heater is highly suitable for a variety of applications, especially when you need a thin, fast-response heating solution that can provide precise heat distribution.
When the following situations apply, a polyimide heater may be a good choice:
1.Silicone rubber or other flexible layered materials cannot be used.
2.High power density (watt density) is required.
3.Chemical exposure is necessary.
4.Deflating may cause contamination, fogging or other undesirable problems.
5.Exposure to radiation, such as in satellites.
Polyimide heaters can also be clamped onto their heating surfaces,then, fix the pressure plate in place. To ensure uniform heat distribution and protect the polyimide heater, it is recommended to use pressure pads or insulation layers. The working surface should have no debris, dirt, chemicals, protrusions or grooves. This will protect the polyimide heater and prevent overheating.
Advantage
Compact and efficient:it is small in size and light in weight. It is not only easy to carry but also can reach a high temperature in a short period of time.
High efficiency and energy saving: The high power density polyimide film heater heats up by utilizing the heat generated through friction when an electric current passes through the film. It does not require preheating and can quickly reach high temperatures, achieving high efficiency and energy savings.
Safe and reliable: The film heater is made of polyimide material, which has excellent high-temperature resistance and insulation properties. It is safe and reliable to use.
